Anomaly detection with Convolutional Graph Neural Networks
Oliver Atkinson, Akanksha Bhardwaj, Christoph Englert +2
We devise an autoencoder based strategy to facilitate anomaly detection for boosted jets, employing Graph Neural Networks (GNNs) to do so. To overcome known limitations of GNN auto…
Invisible Higgs search through Vector Boson Fusion: A deep learning approach
Vishal S. Ngairangbam, Akanksha Bhardwaj, Partha Konar +1
Vector boson fusion proposed initially as an alternative channel for finding heavy Higgs has now established itself as a crucial search scheme to probe different properties of the…
Boosted jet techniques for a supersymmetric scenario with gravitino LSP
Akanksha Bhardwaj, Juhi Dutta, Partha Konar +2
Search for compressed supersymmetry at multi-TeV scale, in the presence of a light gravitino dark matter, can get sizable uplift while looking into the associated fat-jets with mis…
Probing the inert doublet model using jet substructure with a multivariate analysis
Akanksha Bhardwaj, Partha Konar, Tanumoy Mandal +1
We explore the challenging but phenomenologically interesting hierarchical mass spectrum of the Inert Doublet Model where relatively light dark matter along with much heavier scala…
